  17. Waves and Vibrations • phase velocityThe velocity of propagation of a pure sine wave of infinite extent and infinitesimal amplitude. • photoelectric effectsIn photoelectric effects, electrons are emitted from matter (metals and non-metallic solids, liquids or gases) as a consequence of their absorption of energy from electromagnetic radiation. • physical pendulumA pendulum where the rod or string is not massless, and may have extended size; that is, an arbitrarily-shaped, rigid body swinging by a pivot. In this case, the pendulum's period depends on its moment of inertia around the pivot point. • plane waveA constant-frequency wave whose wavefronts (surfaces of constant phase) are infinite parallel planes of constant peak-to-peak amplitude normal to the phase velocity vector. • powerA measure of the rate of doing work or transferring energy. • rarefactiona reduction in the density of a material, especially that of a fluid • refractive indexThe ratio of the speed of light in air or vacuum to that in another medium. • resonanceThe increase in the amplitude of an oscillation of a system under the influence of a periodic force whose frequency is close to that of the system's natural frequency. • Restoring forceA variable force that gives rise to an equilibrium in a physical system. If the system is perturbed away from the equilibrium, the restoring force will tend to bring the system back toward equilibrium. The restoring force is a function only of position of the mass or particle. It is always directed back toward the equilibrium position of the system • Restoring forceIf the system is perturbed away from the equilibrium, the restoring force will tend to bring the system back toward equilibrium. The restoring force is a function only of position of the mass or particle. It is always directed back toward the equilibrium position of the system.An example is the action of a spring. An idealized spring exerts a force that is proportional to the amount of deformation of the spring from its equilibrium length, exerted in a direction to oppose the deformation. Pulling the spring to a greater length causes it to exert a force that brings the spring back toward its equilibrium length. The amount of force can be determined by multiplying the spring constant of the spring by the amount of stretch. • simple harmonic motion(SHM) — Oscillating motion (as of a pendulum) in which the acceleration of the oscillator has an equal magnitude but opposite direction to the displacement of it from the equilibrium position. • simple harmonic oscillatorA device that implements Hooke's law, such as a mass that is attached to a spring, with the other end of the spring being connected to a rigid support, such as a wall.

Waves and Vibrations • simple pendulumA hypothetical pendulum consisting of a weight suspended by a weightless string. • sinusoidalIn the form of a wave, especially one whose amplitude varies in proportion to the sine of some variable (such as time). • Snell's lawA formula used to describe the relationship between the angles of incidence and refraction. • speed of propagationThe speed at which a wave moves through a medium. • standing waveA wave form which occurs in a limited, fixed medium in such a way that the reflected wave coincides with the produced wave. A common example is the vibration of the strings on a musical stringed instrument. • superpositionThe summing of two or more field contributions occupying the same space. • superpositionThe summing of two or more field contributions occupying the same space. • transverse waveAny wave in which the direction of disturbance is perpendicular to the direction of travel. • transverse waveAny wave in which the direction of disturbance is perpendicular to the direction of travel. • transverse waveAny wave in which the direction of disturbance is perpendicular to the direction of travel. • troughA long, narrow depression between waves or ridges. • ultrasoundSound with a frequency greater than the upper limit of human hearing; approximately 20 kilohertz.

" • uniform circular motionMovement around a circular path with constant speed. • waveA moving disturbance in the energy level of a field. • wave equationAn important second-order linear partial differential equation for the description of waves such as sound waves, light waves, and water waves. • wave speedThe absolute value of the velocity at which the phase of any one frequency component of the wave travels. • waveformThe shape of a physical wave, such as sound or electromagnetic radiation. The shape can be any function that repeats in space. • wavelengthThe length of a single cycle of a wave, as measured by the distance between one peak or trough of a wave and the next; it is often designated in physics as λ, and corresponds to the velocity of the wave divided by its frequency. • wavelengthThe length of a single cycle of a wave, as measured by the distance between one peak or trough of a wave and the next; it is often designated in physics as λ, and corresponds to the velocity of the wave divided by its frequency. • workA measure of energy expended in moving an object; most commonly, force times displacement.
